Add an option to disable the requirement of ‘member confirmation’ processes when ‘Domain Verification’ is used, the member email address matches the domain, and the user has been invited to join the organisation.
Seems apparent to me, that in this scenario there is no need for an ‘approval’ as they’ve been invited and are obviously a member of the organisation. Perhaps, also add a new email notification to Owner and Admin role users that this user has joined the Organisation. Just for informational sake.
